Evolution of coherence and non-classicality under global environmental interaction

Understand

A master equation has been constructed for a global system-bath interaction both in the absence as well as presence of non-Markovian noise.

• For the memoryless case, it has been exactly solved for a paradigmatic class of two qubit states in high and zero temperature thermal environment.
• For the non-Markovian model, it has been solved for zero temperature bath.
• The evolution of quantum coherence and entanglement has been observed in presence of the above mentioned interactions.
